Why it matters
Why Azure Networking matters
Azure networking is not just about connecting resources. It is about controlling traffic flow, isolating workloads, reducing exposure, improving performance, building hybrid architectures, and supporting production-grade applications across regions and environments. Whether you are deploying a private application, publishing a web platform, connecting an on-premises datacenter, or troubleshooting routing issues, Azure networking services are central to the design.
Core networking foundations
Core Networking
These are the main Azure networking building blocks. They define address space, segmentation, routing, private connectivity, and foundational communication patterns inside Azure.
Azure Subnets
Subnets divide a VNet into smaller address ranges so workloads can be grouped by function, security, policy, or architecture requirements.
Read guide →Network Security Groups (NSG)
NSGs control inbound and outbound traffic using rules based on source, destination, protocol, and port.
Read guide →Route Tables (UDR)
User-defined routes help direct traffic to firewalls, appliances, VPN gateways, or specific network paths instead of default system routes.
Read guide →VNet Peering
VNet peering privately connects virtual networks with high performance and low latency inside Azure.
Read guide →Azure Private Link
Private Link allows private access to supported Azure services and customer-owned services without exposing traffic to the public internet.
Read guide →Azure Private Endpoint
Private Endpoints bring Azure PaaS services into your VNet using a private IP, improving isolation and compliance.
Read guide →Azure NAT Gateway
NAT Gateway provides controlled outbound internet access for private resources without assigning public IPs directly to each workload.
Read guide →Azure DNS
Azure DNS hosts public DNS zones in Azure and helps manage authoritative name resolution at cloud scale.
Read guide →Traffic delivery and entry services
Load Balancing and Traffic Delivery
These services handle traffic distribution, application publishing, global performance, and entry points for web-facing workloads.
Azure Load Balancer
A high-performance Layer 4 service that distributes TCP and UDP traffic across backend instances.
Read guide →Azure Application Gateway
A Layer 7 load balancer for HTTP and HTTPS traffic with routing, SSL termination, and optional web application firewall features.
Read guide →Azure Front Door
Azure Front Door is used for global application acceleration, edge routing, and secure entry for distributed web applications.
Read guide →Azure Traffic Manager
Traffic Manager routes users to endpoints based on DNS methods such as priority, weighted, performance, or geographic routing.
Read guide →Hybrid and enterprise connectivity
Hybrid Connectivity
Hybrid networking services connect Azure to branch offices, datacenters, remote users, and enterprise WAN architectures.
Azure VPN Gateway
VPN Gateway enables encrypted connectivity between Azure and on-premises environments or remote users across the internet.
Read guide →Azure ExpressRoute
ExpressRoute provides private dedicated connectivity into Azure for enterprises that need lower latency, privacy, and predictable performance.
Read guide →Azure Virtual WAN
Virtual WAN centralizes branch, remote user, VPN, and ExpressRoute connectivity for large-scale enterprise network design.
Read guide →Security and protected access
Security and Protected Access
These Azure services help protect workloads, filter traffic, reduce exposure, and provide safer administrative access models.
Azure Firewall
Azure Firewall is a managed network security service for central traffic inspection, filtering, and policy enforcement.
Read guide →Azure DDoS Protection
DDoS Protection helps defend public-facing Azure resources from volumetric and protocol attacks.
Read guide →Azure Bastion
Azure Bastion provides browser-based secure access to virtual machines without exposing public IP addresses on the VMs.
Read guide →Monitoring and troubleshooting
Monitoring and Troubleshooting
Visibility matters in cloud networking. These services help inspect paths, validate communication, monitor health, and understand traffic behavior.
Azure Network Watcher
Network Watcher gives operational visibility into Azure network resources and supports troubleshooting workflows.
Read guide →Connection Monitor
Connection Monitor tracks reachability and performance between endpoints so engineers can detect network issues early.
Read guide →NSG Flow Logs
NSG Flow Logs help analyze allowed and denied traffic patterns for troubleshooting, auditing, and security visibility.
Read guide →Official documentation
Official Azure networking documentation
